This is a block diagram of two sets of data. The top line is the maximum value and the bottom line is the minimum value. The upper quartile is the upper quartile, the lower quartile is the lower quartile, and the black line in the middle is the median. The height of this box is a quarter of the distance.

However, please note that there is an abnormal value in the second picture, in which case the top line is no longer the maximum value.
